It uses advanced signal processing techniques to achieve the very highest quality of video when converting between standards with different frame rates. So that Cifer can be used in many broadcast installations that have to handle a wide variety of standards; it can also convert between standards of the same frame rate. This makes it a device that can provide outstanding pictures from a source of almost any standard, and as well as providing frame rate conversion it also replaces Up, Down and Cross Converters and in some cases Aspect ratio Converters. Since some installations do not need to produce High Definition (HD) there is an economical version of the converter, Cifer/SD, which can only produce Standard Definition (SD) signals on its output. This version can still process HD signals on its input, but can only produce SD output signals. This could be used, for example, in a SD play out facility where the input signal could be any standard but only an SD output is needed. In this type of application Cifer/SD can replace the need for separate SD Frame Rate, Up and Down converters. Cifer and Cifer/SD are both a part of the Vistek V1600 range of modular products. Unlike some of the simpler modules in the range there are two physical processing modules; one provides the video interfacing, processing and control, while the other provides the real time Motion Estimation needed for the Frame Rate Conversion. Each one of these cards needs a fan card beside it to maintain the necessary temperature operating range, so that a basic Video Cifer occupies four slots in the standard Vistek V1606 Frame. It is therefore possible to fit three Cifers in a 3U rack and still have two spare positions. An optional Audio Processing card, the V6302, is also available. While this is an independent module in its own right it can be fitted immediately next to the Cifer modules, with a shared passive rear module, so that there is tight coupling between them. For example embedded digital audio can be extracted from the input video, processed (which might include decoding of Dolby E surround sound) and then embedded onto the output video. In particular the audio is delayed so as to maintain lip-sync with the video. Cifer also handles many other forms of auxiliary data, such as Closed Captions, Source Identification and Time Code. For the rest of this document any reference to CIFR also applies to Cifer/SD unless explicitly stated otherwise. 4 HU-CIFER Vistek Cifer HD Video Converter 2 Installation 2.1 Assembly Cifer normally occupies five slots in the V1606 Frame, which includes the V6302 Advanced Audio Processing module. They modules in the group should be mounted into the rack as shown here: The rear module must be fitted before any of the main modules can be inserted. For normal operation it is important that both Fan modules, V6991, are fitted. However for short periods, say up to about 5 minutes in a normal working environment Cifer can be operated without one or the other fans. This could be useful in the case of the fans being replaced during maintenance. As with all V1606 Modular Frame installations the modules should be distributed evenly across the fourteen available slots to satisfy the cooling requirements. Clearly this does not apply within the Cifer group of modules, but any other modules in the frame should follow this recommendation. If there are spaces in the frame then they should generally be on the Issue 2.0 5 Vistek Cifer HD Video Converter left, when viewed from the front, and not on the right near the Power Supplies. 2.2 Rear Panel This drawing shows the rear view of the V16HR3G five position Rear Panel for Cifer.

Analog signals are converted to digital form and are then frame synchronized to a user-supplied video reference signal. When the digital input is selected, it too is synchronized to the reference input. Time Base Error Correction is provided, allowing the use of non-synchronous sources such as consumer VTRs and DVD players. An internal test signal generator will produce Color Bars and the pathological checkfield test signals. The processed signal is output as a serial digital component television signal in accordance with ITU-R 601 in both electrical and optical form. Front panel controls permit the user to monitor input and reference status, proper optical laser operation, select video inputs and TBC/Frame Sync function, and adjust video level. Control and monitoring can also be done using the BrightEye PC or BrightEye Mac application from a personal computer with USB support.

  • Rec. 709 Color Space
    Standards, HDR, and Colorspace Alan C. Brawn Principal, Brawn Consulting Introduction • Lets begin with a true/false question: Are high dynamic range (HDR) and wide color gamut (WCG) the next big things in displays? • If you answered “true”, then you get a gold star! • The concept of HDR has been around for years, but this technology (combined with advances in content) is now available at the reseller of your choice. • Halfway through 2017, all major display manufacturers started bringing out both midrange and high-end displays that have high dynamic range capabilities. • Just as importantly, HDR content is becoming more common, with UHD Blu-Ray and streaming services like Netflix. • Are these technologies worth the market hype? • Lets spend the next hour or so and find out. Broadcast Standards Evolution of Broadcast - NTSC • The first NTSC (National Television Standards Committee) broadcast standard was developed in 1941, and had no provision for color. • In 1953, a second NTSC standard was adopted, which allowed for color television broadcasting. This was designed to be compatible with existing black-and-white receivers. • NTSC was the first widely adopted broadcast color system and remained dominant until the early 2000s, when it started to be replaced with different digital standards such as ATSC. Evolution of Broadcast - ATSC 1.0 • Advanced Television Systems Committee (ATSC) standards are a set of broadcast standards for digital television transmission over the air (OTA), replacing the analog NTSC standard. • The ATSC standards were developed in the early 1990s by the Grand Alliance, a consortium of electronics and telecommunications companies assembled to develop a specification for what is now known as HDTV.
